 Hi, I'm Dr. Olyth Selvan, Consulant Heptologist and Chairman Division of Liver Transplantation, Manipal Hospitals, Bangalore. In terms of food for the healthy liver, it can be both a vegetarian diet or a non-vegetarian diet provided it has got a healthy mixture of all the initial nutrients. There is no difference between vegetarian diet or a non-vegetarian diet in causing liver damage and there are known substances which can make the liver better when it's diseased. So there are no herbal medications or naturally occurring medicines which have been proven scientifically to improve liver in a damaged condition. People do take different kind of medications especially leafy medications and preparations made from green leaf herbal medicines but they don't have a scientific basis so far.
